Die Erfindung betrifft eine Start-Stopp-Automatik für ein Kraftfahrzeug mit den Merkmalen des Anspruchs 1.The invention relates to a start-stop system for a motor vehicle with the features of claim 1.
Bei herkömmlichen Fahrzeugen läuft der Motor bei stehendem Fahrzeug, beispielsweise an einer Ampel oder im Stau, im Leerlauf. Dabei wird unnötig Kraftstoff verbraucht und es werden unnötige Emissionen verursacht. Es ist daher bekannt und wird beispielsweise in der DE-OS- 103 31 240 beschrieben, in einem Fahrzeug ein Steuergerät zur Steuerung eines Start-Stopp-Betriebes des Motors einzusetzen, das ein entsprechendes Start-Stopp- Verfahren betreibt und den Motor beim Vorliegen bestimmter Bedingungen abschaltet. Diese Bedingungen zur Durchführung des Start-Stopp-Betriebs umfassen beispielsweise die Erkennung, dass ein Rollen des Kraftfahrzeugs ohne Drehmomentanforderung durch den Fahrer vorliegt. Der Motor wird neu gestartet, wenn wenigstens eines der dem Steuergerät zugeführten Signal eine zweite Bedingung erfüllt, die beispielsweise eine Drehmomentanforderung durch den Fahrer umfassen. In Ausgestaltungen des bekannten Start-Stopp-Betriebs werden weitere Bedingungen ermittelt, beispielsweise wird dieIn conventional vehicles, the engine is idling when the vehicle is stationary, for example at a traffic light or in a traffic jam. This unnecessarily consumes fuel and causes unnecessary emissions. It is therefore known and described for example in DE-OS 103 31 240 to use in a vehicle, a control unit for controlling a start-stop operation of the engine, which operates a corresponding start-stop method and the engine in the presence of certain Conditions off. These conditions for carrying out the start-stop operation include, for example, the detection that there is a rolling of the motor vehicle without a torque request by the driver. The engine is restarted when at least one of the signal applied to the controller meets a second condition, including, for example, a torque request by the driver. In embodiments of the known start-stop operation further conditions are determined, for example, the
Betriebsbereitschaft sicherheitsrelevanter Teilsysteme des Kraftfahrzeugs zwingend gefordert. Dabei wird insbesondere auch der Zustand des elektrischen Bordnetzes des Fahrzeugs berücksichtigt und bei schlechtem Bordnetzzustand auf den Start-Stopp- Betrieb verzichtet.Operational readiness of safety-relevant subsystems of the motor vehicle mandatory. In this case, in particular, the state of the electrical system of the vehicle is taken into account and renounced in poor on-board condition on the start-stop operation.
Bei Fahrzeugen mit Dieselmotoren werden heute Dieselpartikelfilter im Abgastrakt des Motors eingesetzt. Bei derartigen Anordnungen werden die Dieselpartikelfilter zweckmäßigerweise zu bestimmten Zeiten einer Regeneration unterzogen. Bei der Regeneration wird zumindest ein Teil des Dieselpartikelfilters durch Aufheizung des zugeführten Luftstroms regeneriert. Die Aufheizung wird elektrisch oder auch fossil betrieben und beheizt und erwärmt den Dieselpartikelfϊlter und den hierin eingelagerten Dieselruß. Wird die Entflammtemperatur des Dieselrußes erreicht, verbrennt dieser und kann mit Hilfe eines Gebläses vom Partikelfϊlter entfernt werden. Das Dieselpartikelfϊlter wird dadurch regeneriert. Verfahren bzw. Vorrichtungen zur Regeneration von Dieselpartikelfϊltern werden beispielsweise in der DE-OS 101 58 569 beschrieben.In vehicles with diesel engines today diesel particulate filter are used in the exhaust tract of the engine. In such arrangements, the diesel particulate filters are conveniently subjected to regeneration at certain times. During the regeneration, at least part of the diesel particulate filter is regenerated by heating the supplied air stream. The heating is electric or fossil operates and heats and heats the diesel particulate filter and the diesel soot stored therein. If the ignition temperature of the diesel soot is reached, it burns and can be removed from the particle filter with the aid of a blower. The Dieselpartikelfϊlter is thereby regenerated. Methods and devices for the regeneration of Dieselpartikelfϊltern are described for example in DE-OS 101 58 569.

After completion of the regeneration phase, a start-stop function can be provided again and the stop function can be released given predefinable further conditions.
Weiter Vorteile der Erfindung werden durch die in den Unteransprüchen angegebenen Maßnahmen erzielt. Dabei ist besonders vorteilhaft, dass die Entscheidung, ob eine Abschaltung des Motors sinnvoll ist oder nicht, auch von der Zeitdauer, die das Fahrzeug steht, sowie gegebenenfalls abhängig von anderen Größen gemacht wird. Diese Größen können in vorteilhafter Weise ausgewählt werden und umfassen beispielsweise die Motortemperatur, die Außentemperatur, den Zustand des elektrischen Bordnetzes sowie gegebenenfalls weitere Größen oder Bedingungen. Da die benötigten Informationen im Motorsteuergerät, beispielsweise einer Elektronischen Diesel Steuerung (EDC) alle ohnehin vorhanden sind, ist der zusätzliche Aufwand vorteilhafterweise sehr gering.Further advantages of the invention are achieved by the measures specified in the dependent claims. It is particularly advantageous that the decision whether a shutdown of the engine makes sense or not, also of the period of time that the vehicle is, and optionally made dependent on other variables. These variables can be selected in an advantageous manner and include, for example, the engine temperature, the outside temperature, the state of the electrical system and possibly other sizes or conditions. Since the required information in the engine control unit, such as an electronic diesel control (EDC) are all present anyway, the additional cost is advantageously very low.
In einer weiteren besonders vorteilhaften Ausgestaltung wird applizierbarer Koordinator erstellt, der in Abhängigkeit der vorgegebenen Größen entscheidet, ob der Motor bei stehendem Fahrzeug abgestellt wird oder nicht bzw. ob die Start-Stopp-Funktion aktiviert werden soll oder nicht. In einer weiteren vorteilhaften Ausgestaltung kann dieIn a further particularly advantageous embodiment, an applicable coordinator is created, which decides depending on the predetermined variables, whether the engine is turned off when the vehicle is stationary or not or whether the start-stop function is to be activated or not. In a further advantageous embodiment, the
Abschaltung durch den Fahrer durch Betätigung eines Tasters manuell erfolgen, wobei Prioritäten für die Untersuchung bestimmter Kriterien oder die Betätigung des Tasters vergeben werden können. In weiter vorteilhafter Weise wird bei gewünschtem Abschalten des Motors ein Abschaltbit gesetzt. Dieses Abschaltbit wird beispielsweise gesetzt, wenn in einem Kennfeld der Abhängigkeit von Motor- und Außentemperatur eine 1 steht und wenn keine Regeneration des Abgasfϊlters vorliegt sowie eine Bordnetzfunktion eine Freigabe erteilt. Die Bordnetzfunktion umfasst in vorteilhafter Wiese den Zustand des Bordnetztes, den Ladezustand der Batterie, eingeschaltete elektrische Verbraucher usw. und gibt davon abhängig eine Freigabe. Weitere Größen können berücksichtigt werden.Shutdown by the driver by pressing a button manually, whereby priorities for the examination of certain criteria or the operation of the button can be assigned. In a further advantageous manner, a switch-off bit is set when the motor is switched off.

Beschreibungdescription
Das in der Figur dargestellte Ausführungsbeispiel beschreibt einen Zustandsautomaten Z für einen intelligenten Start-Stopp-Betrieb insbesondere bei einem Dieselmotor mit regenerierbarem Partikelfilter, das im Verbrennungstrakt des Motors angeordnet ist. Die Motorsteuerung sowie die Ansteuerungen für die Filterregeneration werden von einem Steuergerät unter Berücksichtigung von beispielsweise mittels verschiedener Sensoren ermittelter Größen durchgeführt. Der Zustandsautomat kann Bestandteil eines eigenen Steuergerätes sein oder Bestandteil des Motorsteuergeräts.The embodiment shown in the figure describes a state machine Z for an intelligent start-stop operation, in particular in a diesel engine with regenerable particulate filter, which is arranged in the combustion tract of the engine. The engine control and the controls for the filter regeneration are performed by a control unit taking into account, for example, by means of various sensors determined variables. The state machine can be part of its own control unit or part of the engine control unit.
Im Einzelnen werden für den Zustandsautomaten Z vier Zustände definiert, zwischen denen noch zu beschreibende Zustandsübergänge stattfinden. Der Zustand 1 bedeutetIn detail, four states are defined for the state machine Z, between which state transitions still to be described take place. State 1 means
Motor aus. Im Zustand 2 ist der Motor temporär aus (Abschaltung erfolgt über Start- Stopp-Betrieb). Zustand 3 beschreibt einen Zustand, bei dem der Motor eingeschaltet ist und normal läuft und Zustand 4 charakterisiert einen Zustand, bei dem der Motor eingeschaltet ist und das Dieselpartikelfilter im Regenerationsbetrieb ist.Engine off. In state 2, the motor is temporarily off (shutdown via start-stop operation). State 3 describes a state in which the engine is on and running normally, and State 4 characterizes a state in which the engine is on and the diesel particulate filter is in regeneration mode.
Die Zustandsübergänge lassen sich wie folgt definieren: Zustandsübergang A:The state transitions can be defined as follows: State transition A:
Das Fahrzeug steht eine applizierbare Zeit und das Abschaltbit ist gesetzt. Das Abschaltbit wird dabei gesetzt, wenn in einem Kennfeld in Abhängigkeit von Motor- und Außentemperatur eine 1 steht, die Abschaltung nicht manuell deaktiviert wurde und eineThe vehicle has an applicable time and the switch-off bit is set. The switch-off is set when a 1 in a map depending on the engine and outdoor temperature, the shutdown was not manually disabled and a
Bordnetzfunktion eine Freigaben erteilt. Die Bordnetzfunktion ermittelt dabei den Zustand des Bordnetzes, unter anderem den Ladezustand der Batterie, wie viele und welche elektrische Verbraucher eingeschaltet sind usw. und gibt davon abhängig eine Freigabe. Weitere Größen können gegebenenfalls noch berücksichtigt werden. Außerdem kann der Zustandsübergang A vom Fahrer manuell hervorgerufen werden, beispielsweise mittels eines Tasters oder eines ähnlichen Bauteils. Im Zustandsautomat findet der Übergang A zwischen dem Zustand 3 und dem Zustand 2 statt.On-board network function issued a release. The electrical system function determines the state of the electrical system, including the state of charge of the battery, how many and which electrical consumers are turned on, etc., and depending on a release. Other sizes may still be considered. In addition, the state transition A can be caused manually by the driver, for example by means of a button or a similar component. In state machine transition A between state 3 and state 2 takes place.
Der Zustandübergang B:The state transition B:
Der Zustandübergang B wird durch Antippen des Gaspedals, das Einlegen eines Gangs oder das Betätigen eines Startschalters oder Start-Taster ausgelöst. Der Zustandsübergang B findet zwischen dem Zustand 2 und dem Zustand 3 statt.The state transition B is triggered by tapping the accelerator pedal, engaging a gear or pressing a start switch or start button. The state transition B takes place between state 2 and state 3.
Zustandsübergang C:State transition C:
Wenn die Beladung des Dieselpartikelfϊlters DPF eine gewisse Grenze überschritten hat und der Betriebszustand des Dieselmotors so ist, dass ein Übergang in den Regenerationsbetrieb erlaubt wird, erfolgt der Zustandsübergang C zwischen dem Zustand 3 und dem Zustand 4.If the load of the diesel particulate filter DPF has exceeded a certain limit and the operating state of the diesel engine is such that a transition to the regeneration mode is allowed, the state transition C takes place between state 3 and state 4.
Zustandübergang D:State transition D:
Der Zustandübergang D zwischen den Zuständen 4 und 3 erfolgt sofern die Regeneration beendet ist.The state transition D between the states 4 and 3 takes place if the regeneration has ended.
Zustandsübergänge E, F und G:State transitions E, F and G:
Die Zustandsübergänge E, F und G bedeuten eine Abschaltung des Motors über den Zündschlüssel und damit einen Übergang von den Zuständen 2, 3 und 4 in den Zustand 1. Zustandsübergang H:The state transitions E, F and G signify a shutdown of the engine via the ignition key and thus a transition from states 2, 3 and 4 to state 1. State transition H:
Der Zustandsübergang H steht für Motoranlassen und stellt den Übergang von Zustand 1 nach Zustand 3 dar.The state transition H stands for engine start and represents the transition from state 1 to state 3.
Mit der dargestellten Zustandsfunktion ist es möglich, abhängig von verschiedenen Randbedingungen unter Berücksichtigung wirtschaftlicher Bedingungen bzw. aus Sicht der Abgasemission den Motor bei stehendem Fahrzeug abzuschalten. Bei Antippen desWith the illustrated state function, it is possible, depending on various boundary conditions, taking into account economic conditions or from the perspective of the exhaust emission to shut off the engine when the vehicle is stationary. When tapping the
Gaspedals bzw. durch Betätigung eines Tasters am Lenkrad kann der Motor vom Fahrer wieder gestartet werden.Accelerators or by pressing a button on the steering wheel, the engine can be restarted by the driver.
Die Entscheidung, ob eine Abschaltung des Motors sinnvoll ist bzw. ob die Start-Stopp- Funktion aktiviert werden soll, hängt neben der Zeitdauer, die das Fahrzeug steht, auch von anderen Größen ab. Wesentlich ist, dass als wichtigstes Entscheidungskriterium der Regenerationsbetrieb dient und bei vorliegendem bzw. erkanntem Regenerationsbetrieb der Motor nicht abgeschaltet wird oder die Start-Stopp-Funktion nicht aktiviert wird oder deaktiviert bleibt.The decision whether a shutdown of the engine makes sense or whether the start-stop function is to be activated depends not only on the length of time the vehicle is standing, but also on other variables. It is essential that the regeneration mode serves as the most important decision criterion and in the present or recognized regeneration mode the engine is not switched off or the start-stop function is not activated or remains deactivated.
Durch den applizierbaren Koordinator bzw. den Zusatandsautomaten, der in Abhängigkeit von den auszuwertenden Größen entscheidet, ob der Motor bei stehendem Motor abgestellt wird oder nicht, lässt sich eine optimale Start-Stopp-Funktion realisieren. Da die Zeit, die das Fahrzeug steht auch eine wesentliche Rolle bei der Entscheidung über eine mögliche Abschaltung spielt, sollte der Fahrer einerseits manuell hervorrufen können und andererseits eine vorgesehene Abschaltung manuell blockieren können. By the applicable coordinator or the additional automatic machine, which decides depending on the variables to be evaluated, whether the engine is stopped when the engine is stopped or not, can realize an optimal start-stop function. Since the time that the vehicle is also playing an essential role in the decision on a possible shutdown, the driver should be able to cause both manually and on the other hand manually block an intended shutdown.
